cvsnt and/or wincvs cannot commit files from different folders at once. therefore on commit first check if a changeset with the same commit log exists within the last five minutes. if so append the files to that changeset. if not insert a new changeset.

The regular expression introduced in [7378] is corrected now for tokenization
to finally match expectations with respect to the particular behavior:
All included tests pass now. Thanks to Jun Omae for the patch.

cloud_mincount allows to cut default cloud size and reduce cluttering
and render time for the /tags page a bit when tagging is in heavy use.
Calls of wiki macro TagCloud are not affected by this configuration option.

Sure, adding argument parsing for this macro as well has been a prerequisite.

Then, on re-designing the list builder algorithm, I introduced linebreaks for
better readability of HTML source. While this removes the fix from [7380],
linebreaks prevent IE from running tags together inside the cloud equally well.

As a tribute to #4503 the mincount check could yield a significant speedup for
the list built by throwing (possibly many) tags with single occurrence away.
Obsolete tag list length calulation saves a few more milliseconds here.
No wait, just joking at the last one. New test in the loop eats up that gain,
and more.
